I have a Yamaha Champ with an ebay 60cc. top end kit. I have been riding it around the last 2 weeks and trying to get it all broken in. It did overheat after my first ride, but seemed to run okay after. I ran a compression test which showed 120 PSI cold, 100 PSI warm. The compression has since improved after getting the motor more broken in. 130 PSI warm/cold.
Is 130 PSI okay or is that low?
